定量评价纳雍鬃岭矿山生态修复区 30 年间生态环境质量时空演变情况,揭示区域活动状况与生态环境发展规律.选取1990 年、1999 年、2009 年、2019 年 4 期Landsat TM/OLI影像,将湿度、热度、干度、绿度作为评价区域生态环境质量的指标,运用RSEI模型评价分析所选矿山生态修复区在 30 年间的生态环境质量时空变化规律.经过研究分析,评价区域的RSEI表现为先下降后上升的规律,结果表明生态环境质量趋好,而在勺窝镇南部以东、鬃岭镇东南部等矿权集中分布区域,生态环境质量较差,其余区域生态环境质量显著变好.评价结果与发展趋势为相关管理部门对治理区制定科学、合理的生态保护与修复实施方案提供一定数据参考,具有一定的应用价值.
Evaluation of ecological environment quality in Nayongzongling mine ecological restoration area based on remote sensing ecological index
Quantitatively evaluate the spatial and temporal evolution of ecological environment quality in the ecological restoration area of Nayongzongling mine in the past 30 years,and reveal the regional activity status and the development law of the ecological environment.Based on Landsat TM/OLI images from 1990,1999,2009,and 2019,using remote sensing technology,selecting indicators that often reflect the quality of the regional ecological environment,such as humidity,greenness,heat and dryness,and using the remote sensing ecological index RSEI evaluation model to analyze the spatiotemporal changes of ecological environment quality in the ecological restoration area of the Nayongzongling mine over the past 30 years.The research results show that the RSEI in the study area shows a trend of first decline and then rise,and the overall ecological environment quality tends to improve.The areas with poor ecological environment quality are mainly distributed in areas with concentrated mineral rights such as the east of Shaowo Town and the southeast of Zongling Town,and the ecological environment quality of other areas has improved significantly.The evaluation results and development trends provide certain data reference for relevant management departments to formulate scientific and reasonable ecological protection and restoration implementation plans in the governance area,and have certain application value.
